Use the following sequence. 3, 6, 12, 24, 48.
1) Mr. Brust says that the 10th term of the above sequence is 768. Is he right? How do you know?

No, Mr. Brust is not right. The 10th term in the sequence is 1536. I know this because each number is double the previous. So, if I work out the sequence up to the 10th term, I get 1536

Step-by-step explanation:

Term Number in sequence/What it is

1 / 3

2 / 6

3 / 12

4 / 24

5 / 48

6 / 96

7 / 192

8 / 384

9 / 768

10 / 1536

huh? im pretty sure it is in 199

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
